To all whom it may concern:

State of Michigan, have invented certain new and useful Improvements inSweeps for following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to new and useful improvements in sweeps for hayand other presses and comprises various details of construction,combinations and arrangements of parts which will be hereinafter fullydescribed and then specifically defined in the appended claim.

I illustrate my invention in the accompanying drawings, in which Figure1 is a perspective view of the sweep. Fig. 2 is an enlarged top planview vof a portion of the apparatus, and Fig. 3

is a sectional view through the shoe, bolt and grooved platform.

Reference now being had to the details of the drawings by letter, Gdesignates a triangular outlined platform having a cam groove cl formedtherein, said groove being substantially triangular in shape with threecurved legs each terminating in a shouldered portion 1), the latterbeing rounded. A base, designated by letter D, has a pivotal post Yprojecting therefrom upon which said platform is mounted and a socketmember Y upon said pivoted post is adapted to receive the sweep pole towhlch a whifiie tree f is attached. Mounted to travel in said groove isa headedbolt N, the head of which is engaged within an enlarged portionof the groove cl, as shown in Fig. 8 of the drawings, while the shankportion of the bolt projects through the slot and has a shoe 6 fastenedthereto by means of a nut Z.

Mounted upon the shank portion of the bolt is an anti-friction roller m,and L designates a lining to the marginal edges of the contractedportion of the groove and against which said anti-friction roller isadapted to travel. Fixed to one end of the shoe is a cable designed tobe attached to the press, and h designates a groove lead- Specificationof Letters Patent.

ing into the groove (Z, thus affording means Be it known that I,NAPOLEON PIQUELTE, a citizen of the United States, residing at Ohassell,in the county of Houghton and whereby the bolt may be inserted withinthe groove (Z.

In operation, a horse or team being connected to the whiffle tree isadapted to cause the sweep to turn with the platform and, as theplatform turns, the shoe riding in the triangular groove, will be drawntaut three times during a revolution of the platform, the drawing of thecable taut being caused by the bolt engaging the shouldered portions atthe ends of the angles of the groove. hen the cable comes in alinementwith one of the legs of the groove, the cable will be slackened, thisoccurring three times in the revolution of the platform, thus allowingthe necessary slack for supplying additional hay or other matter beingpressed. The anti-friction cylinder upon the shank portion of theprojection of the shoe will be drawn into the adjacent leg of the grooveand, as the latter is cam shaped, the sudden releasing of the pull uponthe cable will be moderated as the antifriction cylinder is drawnthrough the leg of the groove to the next shoulder at the end of thegroove. By the provision of an apparatus of this nature, the stopping ofa horse or team each time it is desired to supply additional material tobe pressed is avoided, thus saving considerable time in the pressingoperation.

\Vhat I claim to be new is A sweep for operating presses, etc.,comprising a triangular outlined rotatable platform, a central postrising therefrom, a sweep fixed to said post, said platform having asubstantially triangular outlined undercut groove, the legs of thegroove each being shaped in a compound curve, an end of each leg of thegroove formed into a pocket extending laterally at the end of anadjacent leg of the groove, a bolt having a head mounted in the undercutportion of said groove and held in place by the overhanging Walls of thegroove, an anti-friction roller mounted upon the shank of said bolt, ashoe upon the outer end of said bolt and resting upon the upper face ofthe platform, as shown and described.

In testimony whereof I hereunto aflix my signature in the presence oftwo witnesses.
